Abstract

A system for autonomously calibrating welding quality by using a spot welding gun includes a spot welding gun configured to fix a welding target during a welding process. The spot welding gun is configured to precisely measure a welding indentation depth and perform autonomous welding quality calibration in response to an applied control signal. The system also includes welding robot equipped with the spot welding gun and configured to move to a designated welding point position, a welding controller configured to control a welding current and a welding time of the spot welding gun and inspect welding quality in real time by monitoring the welding indentation depth and dynamic resistance during the welding process, and a welding quality manager configured to receive a welding quality inspection result from the welding controller, transmit a welding condition feedback change, and control the autonomous welding quality calibration.
